What is the Neural Link?

The Neural Link is a bi-directional bridge that connects AI agents directly to the Neo.mjs runtime. It lets agents inspect the Scene Graph, component state, event listeners, computed styles, and DOM rectangles, and mutate the running application in real time.

Why is Neo.mjs called an Application Engine instead of a framework?

Neo.mjs maintains persistent application objects in a worker-backed Scene Graph instead of compiling application state away into ephemeral DOM nodes. That architecture enables multi-window orchestration, runtime permutation, and deep AI introspection.

What is Context Engineering?

Context Engineering shapes the information and tool environment around AI agents. Neo.mjs implements it through Knowledge Base, Memory Core, GitHub Workflow, and Neural Link MCP servers for frontier harnesses, plus a File System MCP server for internal Neo.ai.Agent local loops.

What is the Neo.mjs Agent OS?

The Neo.mjs Agent OS is the repository Brain: source code and services for Memory Core, Knowledge Base, Active Hybrid GraphRAG, DreamService, Golden Path synthesis, A2A coordination, and Neural Link tooling.

Description

Resolves #9997.

Architectural Impact

Tracks lastActivity per categorised session in SessionService.mjs.
Defensively sorts candidates descending chronologically to cure Zero-State Amnesia when fetching context logs on agent reboot.
Playwright unit tests implemented to verify the positional strictness of the extracted session batch.

Edge Cases

Ensures previous logic properly buckets all iterations even when metadata counts misalign, retaining total safety.

✦ # PR Review Summary

Status: Approved

Excellent work shipping this critical optimization. Sorting the internal session collection prior to the heavy processing pipeline flawlessly ensures that newly booted agents are fed their most recent operational reality first!

📊 Evaluation Metrics

[ARCH_ALIGNMENT]: 100 - Deeply aligned with token efficiency paradigms by prioritizing high-fidelity near-term memories.

[CONTENT_COMPLETENESS]: 100 - Code includes appropriate timestamp assignments, proper array manipulation, and comprehensive unit tests.

[EXECUTION_QUALITY]: 100 - Test-driven implementation using the framework's native SessionSummarization.spec.mjs directly mitigates future sorting regressions.

[PRODUCTIVITY]: 100 - Solved problem immediately on first pass.

[IMPACT]: 80 - Critical stability patch extending framework's robustness across multi-session autonomous persistence boundaries.

[COMPLEXITY]: 30 - Low complexity algorithmic sort with explicit math coverage.

[EFFORT_PROFILE]: Quick Win - High ROI outcome secured with low architectural risk.

🧠 Graph Ingestion Notes

[RETROSPECTIVE]: The "Zero-State Amnesia" condition caused by asynchronous batching over un-sorted object keys has been structurally patched using temporal markers. This forces explicit alignment between the agent's expected chronological history and the system's asynchronous indexing.
